My Advice: Scald; Ice Beam; Aqua Ring; Haze. Give it Leftovers.
Vaporeon is a good wall and excellent Dragon-counter. The lack of movepool variety inherent to the Eevee family doesn't lend Vaporeon particularly well to being a general purpose powerhouse despite its base sp atk. If you really want to use it for that though, I would suggest Scald, Ice Beam, Signal Beam (tutor move) and Shadow Ball.
